Nmap diffing

hello all,


I'll be sharing a helpful Nmap that scans your network everyday.
This will work on a VPS/VM server that is linux or, your personal computer that is linux. 

Replace IP (10.100.100.0/24) with yours...
Code:

Code:

#!/bin/bash
mkdir opt/nmap_diff
d=$(date +%Y-%m-%d)
y=$(date -d yesterday +%Y-%m-%d)
/usr/bin/nmap -T4 -oX /opt/nmap_diff/scan_$d.xml 10.100.100.0/24 > /dev/null 2>&1
if [ -e /opt/nmap_diff/scan_$y.xml ]; then
/usr/bin/ndiff /opt/nmap_diff/scan_%y.xml /opt/nmap_diff/scan_%d.xml > /opt/nmap_diff/diff.txt
fi

Any questions, leave them down below.
